no a standard ak-47 will only fire the 7.62 x 39 cartridge, however there are AK variants that are chambered to fire the 5.56mm round. Galil is one of them also Saiga brand AKs are chambered in various calibers including the 5.56.
5.56 variants of the AK platform are also manufactured by China (Type 84), Russia (both the Saiga and the AK101 and AK102), Finland (Rk.62/76 and Rk.95), Poland (Beryl and Mini Beryl), Serbia (Zastava M21 and others), and Bulgaria (AR-2F and others).
The AK47 fires a CARTRIDGE that is 39 mm long, with a 7.92 mm bullet (even though it is CALLED a 7.62 bullet, it is bigger). Typically the bullet is 123 grains in weight, which makes it about as fat as a 30-06 rifle bullet, but shorter. See the link at the bottom of this page:
No. The AK-47 is only chambered in 7.62x39mm. A 5.56x45mm round would not fit in its chamber. However, the modernized AK-101 is chambered in 5.56mm.
556 mm with stock retracted, 730 mm with stock extended.
There is no 32mm handgun. That would fire a bullet more than an inch in diameter.
It depends on the bullet weights. The 9 mm (AKA 9x19 mm, 9 mm Luger, or 9 mm Parabellum) is faster than the .380 ACP (AKA 9 mm Kurz) except when you compare the lightest .380 bullets to the heaviest 9 mm bullets. If you compare the same bullet weights in each, the 9 mm is always faster.
11.5 mm bullet diameter
The diameter of the bullet casing, measured at 7.3 mm, is 7.3 millimeters.
.0219 inches OR .556 mm (USG)
You do not mention which 9 mm cartridge you are asking about. As the 9mm Luger (parabellum) is the most popular handgun load in the world, I assume this is the one? The maximum listed range is about 2200 metres. Actual distance will vary depending on the grain weight of the bullet (for the 9mm luger, from 100 to 147), barell length, and other factors.
Millimeters, it is the size of the bullet.
Probably 25 gauge, which is .556 mm thick. However, 26 gauge is close too, it is .478 mm thick.
